Patent number: 9000956Abstract: A portable terminal includes a finger sensor that recognizes, in response to contact of a finger, the contact and a movement of the finger; and a conversion unit that converts the movement of the finger recognized by the finger sensor into an input event corresponding to an operation instruction to an application running on the portable terminal. If a period of time from recognition of release of the finger from the finger sensor to recognition of placement of the finger on the finger sensor is less than a predetermined amount of time corresponding to physical limitations of a human, the conversion unit does not convert to the input event the recognition of placement of the finger, and recognition of a movement of the finger until recognition of release of the finger after the recognition of placement of the finger.Type: GrantFiled: April 21, 2011Date of Patent: April 7, 2015Assignee: Fujitsu LimitedInventors: Masayuki Goto, Makoto Hosoi, Hidekazu Ito, Shigefumi Yamada, Yoshihiro Takamatsuya

Patent number: 7447976Abstract: A data transfer apparatus improving data transfer rate regardless of the original transfer mode in a USB interface is disclosed. A computer includes a bulk packet generation unit and an isochronous packet transmission unit. The bulk packet generation unit generates a bulk packet (or a control packet) which is a USB packet and has a predetermined structure including a first data area by describing data which is taken as an object of transfer in the first data area. The isochronous packet transmission unit generates an isochronous packet which is a packet in USB isochronous transfer and has a predetermined structure including a second data area by incorporating at least one bulk packet into the second data area, and isochronously transfers the isochronous packet to the mobile telephone over the USB interface.Type: GrantFiled: July 28, 2005Date of Patent: November 4, 2008Assignee: Fujitsu LimitedInventor: Yoshihiro Takamatsuya

Patent number: 6449681Abstract: A buffer access control circuit to access a buffer which is divided into an upper buffer and a lower buffer which are assigned the same address and a memory unit including the buffer access control circuit. The buffer access control circuit includes latch circuits which store data in response to upper and lower buffer access signals, and a first detection circuit which detects whether data latched by the latch circuits match. A modifying circuit inputs data to the first and second latches or inputs inverted data to the first and second latches when one of the upper and lower buffer access signals is generated and the detection circuit detects a match. In this manner, the buffer access control circuit is used to update an address one by one, without the use of a delay circuit when consecutively accessing the upper and lower buffers.Type: GrantFiled: November 21, 2001Date of Patent: September 10, 2002Assignee: Fujitsu LimitedInventors: Shinkichi Gama, Takeshi Nagase, Yoshiki Okumura, Tomohiro Hayashi, Yoshihiro Takamatsuya

Patent number: 6154808Abstract: A semiconductor memory device has a memory space which includes blocks and each of the blocks includes sectors. The sectors have a data storing region and a flag region. Data stored in a sector is marked as valid or erased, depending on the flags in the flag region. If an even number of the flags in the flag region have a logical value of 1, the data is considered to be erased. The data in each sector may be erased and unerased a number of times, by sequentially altering the value of the flags in the flag region. Data stored in the memory may be erased on a sector-by-sector basis.Type: GrantFiled: May 19, 1998Date of Patent: November 28, 2000Assignee: Fujitsu LimitedInventors: Takeshi Nagase, Shinpei Komatsu, Yoshihiro Takamatsuya
